War is terrible. However, I think we are already seeing a different kind of WWIII playing out. Its not happening with guns and tanks, but its happening on the internet. Cyber warfare is being engaged on a daily basis between countries. In addition, there are countless proxy wars taking place around the world. I don't expect a full on war between superpowers because of the fact that nuclear weapons now exist. They would pretty much destroy each other and there will be no winners.
